I have the same question. I've had my Studio Display for around three years plugged into a Mac Studio and use it every day. I purchased the Studio Display mainly for processing my photo image files in Lightroom, and getting tired of continually needing to calibrate my previous LG display with a calibration puck (and wasting lots of expensive ink and printer paper in the process) when making prints. With my Studio Display I set it up once using one its built-in profiles and haven't touched it since.
I also use my Mac Studio and Studio Display for other regular computer purposes, ie reading the news, writing letters, paying bills, participating in forums, doing research, etc. Even though my display has a 60 Hz refresh rate, I've never noticed that being irritating/flickering or in any way suboptimal (whether viewing a static page or scrolling). Perhaps that has something to do with display phosphor lifetime/decay - just a guess.
I know at another tech forum people make refresh rate out to be a huge deal. I suspect a lot of that is from people needing to criticize Apple daily (going back two decades) in order to feel good by asserting what they believe is some kind of power. Just another guess.
